Product details

KCEICE is a professional hydraulic brand originating from Taiwan, China, with mass-production factories in mainland China. It mainly manufactures interchangeable vane pumps matching the Eaton Vickers V20 series. Its mounting dimensions, oil port configurations and performance parameters are fully compatible with original Vickers products, boasting prominent advantages in cost performance and domestic maintenance services.

2. Model Code Breakdown (following standard Vickers V20 naming rules)

Segment Detailed Explanation

V20 Series: Single-stage balanced fixed-displacement vane pump for general industrial medium-flow applications

1 Mounting form: SAE-standard 2-bolt flange mounting

1st P Inlet port specification: 1.25-inch NPT American pipe thread

13 Displacement code: Geometric displacement of 42.4mL/rev (2.59in³/rev), a high-displacement variant in the V20 lineup

2nd P Outlet port specification: Matched 1.25-inch NPT thread

1 Shaft code: Standard keyed drive shaft

A Pressure grade: Built-in low-pressure relief valve with an initial adjustable range of 1.7MPa (250psi)

11 Structural version: Standard end cover and sealing assembly, clockwise rotation when viewed from the shaft end

3. Core Technical Specifications

1. Displacement: 42.4 mL/r

2. Rated working pressure: 21MPa (210bar), maximum peak withstand pressure up to 17.2MPa (2500psi)

3. Rotational speed range: 500rpm minimum, 2400rpm maximum; commonly used industrial speed: 1200~1800rpm

4. Typical flow rate: Around 76.3L/min at 1800rpm

5. Port configuration: Both inlet and outlet adopt 1¼" NPT American tapered pipe thread

6. Rotation direction: Clockwise (viewed from the shaft end)

7. Compatible fluid: Anti-wear hydraulic oil with kinematic viscosity of 10~40mm²/s, operating temperature from -20℃ to +82℃. Standard seals are made of NBR nitrile rubber; FKM fluororubber is optional for high-temperature working conditions

8. Structural features: 12-vane balanced design to fully offset radial forces, minimizing bearing loads, lowering noise and maintaining stable volumetric efficiency over long service life

4. Structure & Working Principle

4.1 Core Components

- High-strength cast iron pump body and precision cam ring with strong deformation resistance under shock loads

- Floating vane structure: Hydraulic pressure automatically compensates vane wear against the cam ring to restrict internal leakage growth during long-term operation

- Dual-side pressure balance grooves eliminate unbalanced radial forces and greatly extend bearing service life

- End cover with integrated priority/relief valve (A specification) for circuit overload pressure protection

4.2 Operation Logic

The drive shaft rotates the rotor. Driven by centrifugal force and hydraulic pressure, vanes stay tightly attached to the inner wall of the cam ring. The volume of sealed cavities between adjacent vanes changes periodically: oil is sucked in when cavities expand, and pressurized oil is discharged when cavities shrink to deliver continuous hydraulic output. The built-in A-grade relief valve caps the maximum system pressure for overload protection.

5. Key Product Advantages

1. Fully interchangeable: Direct replacement for original Eaton Vickers V20-1P13P-1A-11 without modifying mounting flanges, couplings or pipeline layouts

2. Low noise & low pulsation: 12-vane design cuts flow pulsation, reducing operating noise by 3~8dB compared with conventional vane pumps

3. Dirt resistance & durability: Adaptable to common industrial oil cleanliness standards; wear-coated vanes ensure long service life under heavy-duty cycles

4. Integrated pressure regulation: Onboard relief valve simplifies external valve layouts for more compact hydraulic power units

5. Easy maintenance: Modular construction enables convenient replacement of vanes and seal kits, with abundant domestically-sourced spare parts

6. Typical Application Scenarios

- Light industry machinery: Hydraulic systems for injection molding machines, shoe-making equipment, stretch forming machines and rubber vulcanizers

- Material handling: Forklifts, stackers and lifting platforms

- General machine tools: Hydraulic circuits for lathes, bending machines and shearing machines (feeding and clamping functions)

- Compact construction machinery: Skid steer loaders, road maintenance equipment and agricultural harvesters

- Automated production lines: Packaging machinery, die-casting machines and small-to-medium metallurgical hydraulic stations

Model Code Breakdown

The model number KCEICE V20-1P13P-1A-11 is very likely a misprint or variant designation of the classic Vickers (now Eaton) V20 Series Hydraulic Vane pump. The breakdown is as follows:

· V20 – Pump series, representing a Vickers single, balanced vane pump. It is a classic high-pressure Hydraulic Vane pump widely used in the industry.

· 1 – Number of pump sections. “1” indicates a single pump with only one pumping cartridge, supplying a single flow to the hydraulic system.

· P – Inlet port connection or mounting flange code, typically referring to a standard SAE flange mount for the hydraulic system.

· 13 – Displacement code, corresponding to approximately 13 USGPM (@1200 rpm) or an equivalent displacement level around 13 cm³/rev, making it an ideal mid-range flow choice for a hydraulic system.

· P – Outlet port position/orientation code.

· 1 – Shaft end type, commonly a straight keyed shaft suitable for coupling with an electric motor or internal combustion engine to form the power source of a complete hydraulic system.

· A – Direction of rotation (viewed from shaft end). “A” typically indicates clockwise (right-hand) rotation, which must match the prime mover’s rotation in the hydraulic system.

· 11 – Design series number, representing the seal class and structural revision of this pump, adapted to meet the leakage prevention and durability requirements of modern hydraulic systems.

Core Characteristics as a Hydraulic Vane Pump

When this Hydraulic Vane pump is integrated into your hydraulic system, it delivers the following significant advantages:

· Low noise and low pulsation: The smooth contact between the vanes and the internal cam ring makes the entire hydraulic system run noticeably quieter than with gear pumps.

· Strong self-priming ability and uniform flow, ideal for providing stable pressurized oil to stationary hydraulic systems such as machine tools, injection molding machines, and presses.

· Excellent serviceability: The typical cartridge-type construction allows for quick replacement of wear parts (vanes, port plates) during hydraulic system maintenance, significantly reducing downtime and upkeep costs for the hydraulic system.

· Wide pressure and speed coverage: This Hydraulic Vane pump can achieve continuous operating pressures of 160–210 bar, fully meeting the demands of most industrial hydraulic systems.

Typical Applications in a Hydraulic System

The V20 Series Hydraulic Vane pump has a long-proven track record and is widely used in the following hydraulic systems:

· Clamping and table feed hydraulic systems of machine tools and machining centers

· Mold clamping and injection hydraulic systems of injection molding machines

· Holding pressure hydraulic systems of die-casting machines and presses

· Hydraulic systems for marine steering gear and deck machinery
